Why shouldn't fathers looking after kids on their own have that same opportunity?
>"There is a lack of women in STEM fields." //
The corollary of this is that women can uniquely provide skills in STEM fields that men are unable to provide. Yet it's been hotly denied that men can bring anything to any field that women can't (even as a generality by some). So, in what way is there a lack of women? Are we suddenly allowed to say that a person brings skills to the table simply because of their chromosomes? Personally I don't doubt it but it contradicts exactly the express position of many feminists and undermines entirely the basis for equalising the proportion of each sex employed in a particular field.

Why? Don't we need people to become nurses just as we need people to work in other specialisms?
Suppose practically no women want to be sysadmins, lots of men do and that a certain cadre of nerds (who're perceived as being borderline-autistic) are most able to perform the role; such characters are usually men, these men want to do that job, few women want to do that job ... tell me why we need to incentivise women to do the job? Aren't men capable of doing it? Why does it matter what sex they are?
Provided the choice of job candidates is performed fairly why should we rail against the progress in removing discrimination and add in new types of discrimination?
Ladies Nights are discriminatory. I have no problem with them for private businesses, the minute the government starts running them and claiming that they aren't discriminatory or that they somehow are working against discrimination, that's when the government has gone of the rails.
